Application mea February 1a, 1925.v serial No. 8,736...

v Thepresent invention relates to an electricv 8 between the housings 5. This reel .B inpower reel designed for advanced .mining clud'es the wooden disks 12 which support 55 machinery such as coal loaders, coal cutters, the annular series of rods 13 therebetween. and drilling machinery, that is mining maf Collars llreceive the shaft 8 and are chines which operate in advance of the st a- Vfixed thereto by .set screws 15. Flanges 16V tionary supply trolley system.v The ree-l isY are provided on these. collars 14 and are` y "supplied will current passing'over a flexible', fixed to the disks 1.2 by the bolts 17 so that 60 cable, one end of which is attached to the the reel will rotate with the shaft 8. The trolley wire and the other end 1 attached lto shaft may be actuated in any suitable 'mannerle the reel, the reel beingy directly coupled to and-onev end thereof is squaredv as at .18 in the machine.A l y order that a crank 'maybe engaged thereon The principal object ofthe invention is for-'Inanually turning the'reel, x 65 to provide a reel of this nature possessed The numeralV 19 designates. theV zflexible of simplicity of construction, few part-s cable adapted to bejwoundabout the reel i which are readily accessible, and one which and in the present instancethere ,are twol of is thoroughly reliable and eflicient in operthese cables, the. ends of Awhich l,terminate ation. adjacent thedisks 12 and .are connectedto A still further important object of the inbolt-s 20 extend'ng through the disks and vention is to provide a reel of this nature through the flanges 21 of the collector ring 20 which is strong, durable, inexpensive to conf 22. This collector ring 22 is held in place struct, not liable to readily get out of order, on the outer surfaces of the disks 12 within and otherwise well adapted to the purposes the housings 5 by the bolts 2O and screws 23. for which it is designed. A brush holder H is supported in each of With the above and numerous other obthe housingsv 5 for holdingits brushin enj' 25 jects in view as will appear as the descrip-v gagement with the collector ring 22. The tion proceeds, the invention resides incercable 25 passes through an opening in this tain novel features of construction, and in housing and is connected,v with the holder the combination and arrangement of parts H and is supported by a clamp 26 provided as will be hereinafter more fully described on the side of the housings. l

I all the features of advantage enumeratedasV desirable in the statement of the invention and the above description, but it is desired to point out that the numerous changes in the details of construction, and in the combination and arrangement of parts-inay be resorted to without departing from thespirit or scope of the invention as hereinafterY claimed or sacriicing'any of itsadvantages. Having thus described our" invention, what we claim as new is f L 1 l. In combination, a shaft, a reel rotatable with the shaft, housingshaving bear- The shaft may' ings for the shaft, collector rings on the sides ofthe reel within the housings, brushes supported in the housings in 4engagement with the collector rings, each brush including a holder comprising a body having a recess therein, a pin extending transversely of the recess, a spring engaged with said pin, and

means for turning the pin for tensioning the spring against the brush.

1 2. In a reel structure, a shaft, a pair of housings having bearings receiving the shaft,

areel on the shaft ybetween the housings comprisingarpair of insulating disks, bars carried between the disks aboutV the shaft,

means for fixing the reel to the shaft, a collector ring on the outside of each disk, a

bolt connected to the ring and extending through the adjacent disk, ra brush vin each` housing, means for supporting the brush in Y each housing and insulating it therefrom, a

clamp on the exterior of each housing, wires supportedon said clamps and connectedfto the brushes within the housings. i, l Y In testimony whereof we affix our signatures. f
